[The significance of concomitant internal diseases for hip endoprosthesis in elderly patients].

We studied the importance of internal diseases in 110 patients with an age of more than 70 years. Most of the patient (85%) were handicapped by several diseases with an increasing of the operative risk. Special importance has the prophylaxis of thromboembolism and the elimination of essential local infect. In this way it is possible to avoid essential postoperative complications. There is nearly no restriction of the older patients in reference to the endoprosthesis of the hip if we notice the risk factors and the optimal pre-, intra- and postoperative treatment of the patients.
